Implantable Self‐Powered Systems for Electrical Stimulation Medical Devices

Advanced Science, EarlyView.
In this paper, the design strategy and clinical application of ISS are discussed in depth from four aspects: the design and optimization of the energy collection module, the selection and preparation of adaptive electrode materials, the innovation of system design strategy, and the biological effect of electrical stimulation of ISS.

Parallel evolution of auditory genes for echolocation in bats and toothed whales. [PDF]

PLoS Genetics, 2012
The ability of bats and toothed whales to echolocate is a remarkable case of convergent evolution. Previous genetic studies have documented parallel evolution of nucleotide sequences in Prestin and KCNQ4, both of which are associated with voltage ...

Temporal modulation transfer functions in the European Starling (Sturnus vulgaris): II. Responses of auditory-nerve fibres [PDF]

, 1995
The temporal resolution of cochlear-nerve fibres in the European starling was determined with sinusoidally amplitude-modulated noise stimuli similar to those previously used in a psychoacoustic study in this species (Klump and Okanoya, 1991).

Metabolomic and Cellular Mechanisms of Drug‐Induced Ototoxicity and Nephrotoxicity: Therapeutic Implications of Uric Acid Modulation

Advanced Science, EarlyView.
Drug‐induced renal damage impairs uric acid excretion, causing its accumulation in the serum, which subsequently infiltrates the cochlea. Xanthine oxidase and the ABCG2 transporter, critical in uric acid metabolism and excretion, undergo pathological changes in renal tubular and cochlear stria vascularis cells.

The Cochlear Tuning Curve [PDF]

, 2001
The tuning curve of the cochlea measures how large an input is required to elicit a given output level as a function of the frequency. It is a fundamental object of auditory theory, for it summarizes how to infer what a sound was on the basis of the cochlear output.

Micro‐Coil Neuromodulation at Single‐Cell and Circuit Levels for Inhibiting Natural Neuroactivity, Neutralizing Electric Neural Excitation, and Suppressing Seizures

Advanced Science, EarlyView.
Micromagnetic stimulation (µMS) offers a precise method for neural inhibition, complementing existing neuromodulation techniques. Using an implantable micro‐coil device, µMS selectively suppresses cortical activity with high spatial resolution. It effectively counteracts micro‐electrode stimulation and reduces seizure amplitude, highlighting its ...

Mouse Panx1 Is Dispensable for Hearing Acquisition and Auditory Function [PDF]

, 2017
Panx1 forms plasma membrane channels in brain and several other organs, including the inner ear. Biophysical properties, activation mechanisms and modulators of Panx1 channels have been characterized in detail, however the impact of Panx1 on auditory ...

Immediate and delayed cochlear neuropathy after noise exposure in pubescent mice.

PLoS ONE, 2015
Moderate acoustic overexposure in adult rodents is known to cause acute loss of synapses on sensory inner hair cells (IHCs) and delayed degeneration of the auditory nerve, despite the completely reversible temporary threshold shift (TTS) and ...

Accurate Detection of Inner Ears in Head CTs Using a Deep Volume-to-Volume Regression Network with False Positive Suppression and a Shape-Based Constraint [PDF]

arXiv, 2018
Cochlear implants (CIs) are neural prosthetics which are used to treat patients with hearing loss. CIs use an array of electrodes which are surgically inserted into the cochlea to stimulate the auditory nerve endings. After surgery, CIs need to be programmed.

“Spin‐Rinse and Repeat”: Facile Processing to Improve Cytocompatibility of Poly(3,4‐Ethyelenedioxythiophene): Polystyrene Sulfonate Composites for Bioelectronics

Advanced NanoBiomed Research, EarlyView.
In this article, the concerns surrounding the potential toxicity of excess dopant in commercial widely utilized poly(3,4‐ethyelenedioxythiophene):polystyrene sulfonate formulations in organic bioelectronic applications is addressed. A simple method to remove this excess dopant with the aim of improving material cytocompatibility is presented. Materials
